It features fire resistance, explosion-proof properties, non-combustibility (capable of continuous operation at 250\u00b0C and short-term operation up to 1000\u00b0C for 30 minutes), high current-carrying capacity, small outer diameter, long service life, and generally does not require an independent grounding conductor. As such, it is widely used in hazardous, harsh, and high-temperature environments such as nuclear power plants, metallurgy, chemical industries, mines, and manufacturing.","_b2bpc_model_items":"[{\"label\":\"model\",\"value\":\"Flexible fire-resistant cable without metal conduit\"},{\"label\":\"model\",\"value\":\"Rigid fire-resistant cable\"}]","_b2bpc_inquiry_text":"","_b2bpc_download_url":"","_b2bpc_gallery_ids":"155,156,157,158","_b2bpc_spec_items":"[]","_b2bpc_download_items":"[]","_b2bpc_application_scenarios":"","_b2bpc_recommendation_reason":"","_b2bpc_target_industries":"","_b2bpc_product_advantages":"","_b2bpc_seo_title":"","_b2bpc_seo_description":"","_b2bpc_seo_canonical":"","_b2bpc_seo_noindex":"0","_b2bpc_seo_focus_keyword":"","_b2bpc_seo_long_tail_keywords":"","_b2bpc_seo_faq":""},"b2b_product_category":[],"b2b_product_industry":[],"class_list":["post-149","b2b_product","type-b2b_product","status-publish","has-post-thumbnail","hentry"],"_links":{"self":[{"href":"https:\/\/jinlandianlan.com\/index.php?rest_route=\/wp\/v2\/b2b_product\/149","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/jinlandianlan.com\/index.php?rest_route=\/wp\/v2\/b2b_product"}],"about":[{"href":"https:\/\/jinlandianlan.com\/index.php?rest_route=\/wp\/v2\/types\/b2b_product"}],"version-history":[{"count":2,"href":"https:\/\/jinlandianlan.com\/index.php?rest_route=\/wp\/v2\/b2b_product\/149\/revisions"}],"predecessor-version":[{"id":154,"href":"https:\/\/jinlandianlan.com\/index.php?rest_route=\/wp\/v2\/b2b_product\/149\/revisions\/154"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/jinlandianlan.com\/index.php?rest_route=\/wp\/v2\/media\/155"}],"wp:attachment":[{"href":"https:\/\/jinlandianlan.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=149"}],"wp:term":[{"taxonomy":"b2b_product_category","embeddable":true,"href":"https:\/\/jinlandianlan.com\/index.php?rest_route=%2Fwp%2Fv2%2Fb2b_product_category&post=149"},{"taxonomy":"b2b_product_industry","embeddable":true,"href":"https:\/\/jinlandianlan.com\/index.php?rest_route=%2Fwp%2Fv2%2Fb2b_product_industry&post=149"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
